Php warning Creatingdefaultobjectfromemptyvalue

PHP prompts Creatingdefaultobjectfromemptyvalue, which is generally due to the PHP version upgrade, PHP5.4 or later versions usually report this error. the solution is to find the location where the error is reported and check which variable is used directly without initialization. the variable is first instantiated as an empty class. For example:

The code is as follows:

$ Ct = new stdClass ();

Modify the code of the file, for example:

The code is as follows:

If (! Isset ($ themes [$ current_theme]) {
Delete_option ('current _ theme ');
$ Current_theme = get_current_theme ();
}
$ Ct = new stdClass ();
$ Ct-> name = $ current_theme;

Solve the problem.
